Description
The title of present application for patent opinion application on April 6th, 2009 is the 61/167th of " in wireless communication system, setting up communication session (SETTING UP A COMMUNICATION SESSION WITHIN A WIRELESS COMMUNICATIONS SYSTEM) " the; The priority of No. 081 provisional application case; And said provisional application case transfers this case assignee, and is incorporated herein clearly by reference hereby.
Technical field
Embodiments of the invention relate to sets up communication session in wireless communication system.
Background technology
Wireless communication system is too much generation development, comprises that first generation artificial antenna phone service (1G), the second generation (2G) digital cordless phones service (2.5G and the 2.75G network that comprise transition period) and the third generation (3G) possess high-speed data/Internet function wireless service.There are many dissimilar wireless communication systems that using at present, comprise honeycomb fashion and personal communication service (PCS) system.The instance of known cellular system comprises cellular analog Advanced Mobile Phone System (AMPS); With move connecting system (Global System for Mobile access based on the whole world of code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), TDMA; GSM) digital cellular system of variant, and the hybrid digital communication system of using the renewal of TDMA and two kinds of technology of CDMA.
The method that is used for providing cdma mobile communication in the U.S. by telecommunications industry association/electronic industries association in the TIA/EIA/IS-95-A (being called as IS-95 in this article) that is entitled as " travelling carriage-base station compatible standard (Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum Cellular System) that is used for dual mode wideband spread spectrum cellular system " standardization in addition.The AMPS and the cdma system of combination have been described in TIA/EIA standard I S-98.In IMT-2000/UM or international mobile telecommunication system 2000/ Universal Mobile Telecommunications System, described other communication system, standard contains the standard that is called as wideband CDMA (WCDMA), CDMA2000 (for example, CDMA2000 1xEV-DO standard) or TD-SCDMA.
In wireless communication system, travelling carriage, hand-held set or access terminal (AT) receive the signal from the base station (also being known as cell site or sub-district) of fixed position, and said base station is supported near it or communication link or service in the specific geographic area on every side.The base station provides the inlet point to access network (AN)/radio access network (RAN); Access network (AN)/radio access network (RAN) is generally the packet data network of use based on the agreement of standard internet engineering duty group (IETF), and said agreement support is used for the method that requirement comes differentiated service based on service quality (QoS).Therefore, the base station is mutual and mutual with AN via Internet Protocol (IP) network packet with AT via air interface usually.
In radio telecommunications system, PoC (PTT) ability is just becoming commonly used between service department and consumer.PTT can support " assignment " voice service, and it is via standard commercial wireless infrastructure such as for example CDMA, FDMA, TDMA, GSM and operate.In assignment-type model, the communication between the end points (AT) takes place in virtual group, and the voice of one of them " talker " are transferred to one or more " listeners ".The single-instance of this type communication is commonly referred to as dispatch call, or abbreviates the PTT calling as.PTT calls out and is the illustration to a group, and it defines the characteristic of calling.The information (for example, group name or group identification) that group is tabulated and is associated by the member in essence defines.
Conventionally, the packet in the cordless communication network is through being configured to send to single destination or accessing terminal.Data are called as " clean culture " to the transmission of single destination.Along with mobile communication increases, simultaneously to a plurality of abilities of being transferred to given data of accessing terminal outbalance that become.Therefore, adopted some agreements to support same package or message transfer of data when a plurality of destinations or target access terminal." broadcasting " is meant packet to whole destinations or the transmission of access terminal (for example, in given sub-district, by given service provider service etc.), and " multicast " is meant the transmission of packet to the given destination or the group that accesses terminal.In one example, said given destination group or " multicast group " can comprise more than one and be less than whole possible destinations or access terminal (for example, in given group, by given service provider service etc.).Yet, under some situation, have at least possibility multicast group only to comprise one access terminal (being similar to clean culture), perhaps multicast group comprises all and accessing terminal (for example, in sub-district or sector etc.) (being similar to broadcasting).
Broadcasting and/or multicast can be carried out in wireless communication system in a number of ways, for example carry out a plurality of unicast operation in proper order to adapt to multicast group, distribute unique broadcast/multi broadcast channel (BCH) to be used for disposing simultaneously a plurality of transfer of data or the like.The conventional system that uses broadcast channel to be used for push-to-talk communications is that on March 1st, 2007 and title are described for the open case of No. 2007/0049314 U.S. Patent application of " using the PoC group call system (Push-To-Talk Group Call System Using CDMA 1x-EVDO Cellular Network) of CDMA 1x-EVDO cellular network " on the date, and the mode that the content of the open case of said U.S. Patent application is quoted in full is incorporated herein.Described in No. 2007/0049314 open case, broadcast channel can be used for using the push-to-talk call of conventional signaling technology.Though the use of broadcast channel can improve the bandwidth requirement to conventional unicast technique, the conventional signaling of broadcast channel still possibly cause additional overhead and/or delay, and possibly make system performance degradation.
Third generation partner program 2 (" 3GPP2 ") has defined broadcasting-multicast service (BCMCS) standard of the multi-casting communication that is used for being supported in the CDMA2000 network.Therefore, the date is that the mode that on February 14th, 2006, title are quoted for the version (version 1.0 C.S0054-A) of the BCMCS standard of the 3GPP2 of " CDMA2000 two-forty broadcasting-multicast packet data air interface specification (CDMA2000 High Rate Broadcast-Multicast Packet Data Air Interface SpeciFlcation) " hereby in full is incorporated herein.

Fig. 1 explanation is according to the block diagram of an example embodiment of the wireless system 100 of at least one embodiment of the present invention.System 100 can contain and accesses terminal; For example cellular phone 102; It is communicated by letter with access network or radio access network (RAN) 120 via air interface 104; RAN 120 can with access terminal 102 be connected to packet-switched data network (for example, Intranet, internet and/or carrier network 126) is provided and access terminal 102,108,110, the internuncial network equipment of data between 112.So the place is showed, accessing terminal can be cellular phone 102, personal digital assistant 108, beep-pager 110, and it is shown as two-way text pager herein, or even independent computer platform 112 with wireless communication portal.Therefore; Embodiments of the invention can be realized comprising wireless communication portal or have on any type of the accessing terminal of wireless communication ability; It includes, but is not limited to radio modem, pcmcia card, personal computer, phone, or its any combination or son combination.In addition, as used herein, term " accesses terminal ", " wireless device ", " client terminal device ", " portable terminal " and the interchangeable use of its variant.
Referring to Fig. 1, the assembly and the interelement correlation of the wireless network 100 of example embodiment of the present invention are not limited to illustrated configuration once more.System 100 is merely exemplary and can comprises and allow long-range (for example accessing terminal; Wireless client calculation element 102,108,110,112) to each other and/or the assembly that is connected with RAN 120 via air interface 104 between the two and carry out any system of radio communication between many persons, it includes, but is not limited to carrier network 126, internet and/or other remote server.
RAN 120 controls send to the message (sending as packet usually) of radio network controller (RNC) 122.RNC 122 is responsible for signalings, foundation and dismounting service general packet radio service (GPRS) support node (SGSN) 160 and the Bearer Channel (that is data channel) between 102/108/110/112 of accessing terminal.If launch link layer encryption, RNC 122 also encrypted content before transmitting content via air interface 104 so.The function of RNC 122 is well-known in this technology, and will no longer further discuss for brevity.Carrier network 126 can pass through network, internet and/or public switch telephone network (PSTN) and communicate by letter with RNC 122.Perhaps, RNC 122 can be directly connected to internet or external network.Usually, network between carrier network 126 and the RNC 122 or internet are connected and transmit data, and the PSTN transfers voice information.RNC 122 can be connected to a plurality of base stations (Node B) 124.To be similar to the mode of carrier network, RNC 122 is connected to Node B 124 through network, internet and/or PSTN usually, transmits and/or voice messaging to be used for data.Node B 124 can wireless mode with broadcast data messages to accessing terminal, for example cellular phone 102.So known in the technology, Node B 124, RNC 122 and other assembly can form RAN 120.Yet, also can use alternative arrangements, and the invention is not restricted to illustrated configuration.For instance, in another embodiment, one or more functional single " mixing " module that is reduced in RNC 122 and the Node B 124, it has both functional of RNC 122 and Node B 124.
Fig. 2 explanation is according to the carrier network 126 of the embodiment of the invention.In particular, the assembly of carrier network 126 explanation general packet radio service (GPRS) core networks.In the embodiment of Fig. 2, carrier network 126 comprises Serving GPRS Support Node (SGSN) 160, Gateway GPRS Support Node (GGSN) 165 and internet 175.Yet, should be appreciated that in alternate embodiment, the several portions of internet 175 and/or other assembly can be positioned at the carrier network outside.
Usually, GPRS is the agreement that global system for mobile communications (GSM) phone is used for transmitting internet agreement (IP) bag.GPRS core network (for example GGSN 165 with one or more SGSN 160) is the centralized part of gprs system, and also provides the support based on the 3G network of W-CDMA.The GPRS core network is the integration section of GSM core network, the conveying that mobile management, session management is provided and the bag of the IP in GSM and the W-CDMA network is served.
GPRS tunnelling agreement (GTP) is the definition IP agreement of GPRS core network.GTP moves to another with the end user's (for example, accessing terminal) who allows GSM or W-CDMA network from one to locate, and equally continues to be connected to Internet protocols as a position from GGSN 165 simultaneously.This is through subscriber's data are realized from the GGSN 165 that subscriber's current SSGN 160 is sent to the session of just disposing the subscriber.
The GPRS core network uses the GTP of three kinds of forms; I.e. (i) GTP-U, (ii) GTP-C and (iii) GTP ' (GTP is basic).GTP-U is used for transmitting user data being used for the contextual independent tunnel of each Packet Data Protocol (PDP).GTP-C be used to control signaling (for example, PDP Context set up and the check of deletion, GSN accessibility, for example when subscriber's renewal or modification when a SGSN moves to another SGSN etc.).GTP ' is used for metering data is sent to billing function spare from GSN.
Referring to Fig. 2, GGSN 165 serves as the interface between GPRS backbone network (not shown) and the external packets data network 175.GGSN 165 extracts from the GPRS bag from SGSN 160 has the bag data of the Packet Data Protocol of being associated (PDP) form (for example, IP or PPP), and on the packet data network of correspondence, said bag is sent.On other direction, to import packet into and be directed to SGSN 160 by GGSN 165, SGSN 160 management and control are by the radio access bearer (RAB) of the destination AT of RAN 120 services.Therefore, GGSN 165 is stored in (for example, in PDP Context) in its location register with current SGSN address and his/her profile of target AT.GGSN is responsible for the IP address assignment, and by the default router of connection AT.GGSN also carries out checking and billing function.
In one example, SGSN 160 represents one among the many SGSN in the carrier network 126.Each SGSN be responsible for sending from travelling carriage or the packet of AT gone in the geographical coverage that is associated.The task of SGSN 160 comprises route and transmission, mobile management (for example, attached/separation and location management), Logical Link Management and checking and billing function.For instance; The location register of SGSN will be to all GPRS user position information of SGSN 160 registration (for example; Current area, current VLR) and user profiles (for example, employed pdp address in IMSI, the packet data network) be stored in one or more PDP Contexts that are used for each user or AT.Therefore; SGSN is responsible for (i) and separates the down link GTP bag of tunnelling from GGSN 165, (ii) IP is wrapped to GGSN 165 up link tunnellings, (iii) when AT moves between the SGSN coverage; Carry out mobile management, and (iv) mobile subscriber is opened bill.As be understood by those skilled in the art that except that (i) arrived (iv), the SGSN that is configured for use in the GSM/EDGE network compares with the SGSN that is configured for use in the W-CDMA network had different functions property slightly.
RAN 120 (for example, or in global mobile communication system (UMTS) system architecture for UTRAN) for example uses host-host protocol such as frame relay or IP to communicate by letter with SGSN 160 via the Iu interface.SGSN 160 communicates by letter with GGSN 165 via gn interface, and gn interface is the IP-based interface between SGSN 160 and other SGSN (not shown) and the inner GGSN, and uses the defined GTP agreements of preceding text (for example, GTP-U, GTP-C, GTP ' etc.).Though not shown among Fig. 2, gn interface is also used by domain name system (DNS).GGSN 165 uses the IP agreement directly or through the wireless application protocol (wap) gateway to be connected to public data network (PDN) (not shown) via the Gi interface, and is connected to internet 175 again.
PDP Context is SGSN 160 and GGSN 165 both last data structures that exist, and it contains the communication session information of said AT when specific AT has effective GPRS session.When AT hoped initial GPRS communication session, AT must at first be attached to SGSN 160, and then with GGSN 165 PDP context activating.PDP Context data structure among the SGSN 160 of this distribution subscriber current accessed and the GGSN 165 of the access point of service AT.
For instance, PDP Context can comprise (i) PDP parameter, (ii) identifier, (iii) PDP Context type, and (iv) one or more other fields.For instance, (i) the PDP parameter can comprise the service quality (QoS) of ToS, APN (APN), communication session, the IP address of AT etc.).(ii) identifier can comprise AT at international mobile subscriber identity (IMSI), Network Service Access point identifier (NSAPI) or the endpoint of a tunnel ID (TEID) at SGSN 160 and/or GSGN 165 places (that is, TEID is the numbering by the identification of SGSN and/or the GSN distribution institute tunnelling data relevant with specific PDP Context).About (iii) PDP Context type, will understand, usually existence two types PDP Context of field indication (that is, main and less important) thus.For instance; Main PDP Context comprises unique ip address; And less important PDP Context and at least one other PDP Context share I P address, create (promptly through existing PDP Context; So that share its IP address), and want each time PDP Context can have with and the different QoS set point of another PDP Context that is associated of same AT.In one example, to specific AT, nearly 11 PDP Contexts (for example, having main and less important any combination) can coexist.How by convention hereinafter will provide the instance of PDP context activating about Fig. 4.
Referring to Fig. 3; The accessing terminal 200 (being wireless device here) has platform 202 of cellular phone for example, said platform 202 can receive and carry out from software application, data and/or the order of RAN 120 transmission (its finally can from carrier network 126, internet 175 and/or other remote server and network).Platform 202 can comprise transceiver 206, and it operationally is coupled to application-specific integrated circuit (ASIC) (" ASIC " 208) or other processor, microprocessor, logical circuit or other data processing equipment.ASIC 208 or other processor are carried out any in the memory 212 with wireless device and are stayed be situated between 210 layers of the API (" API ") that connect of the program of depositing.Memory 212 can comprise read-only memory or random access memory (RAM and ROM), EEPROM, flash cards or the general any memory of computer platform.Platform 202 also can comprise local data base 214, and local data base 214 can remain on the application of not using with effective means in the memory 212.Local data base 214 is generally flash memory cells, but can be known any secondary storage in like this technology, for example, and magnetic medium, EEPROM, optical media, tape, floppy disk or hard disk etc.So known in the technology, the assembly of inside panel 202 also operationally is coupled to the for example external device (ED) of antenna 222, display 224, PoC button 228 and keypad 226 and other assembly etc.
Therefore, one embodiment of the invention can comprise a kind of accessing terminal, and said accessing terminal comprises the ability of carrying out the function described in this paper.As be understood by those skilled in the art that various logical elements can discrete elements, any embodied in combination of the software module of on processor, carrying out or software and hardware, and is disclosed herein functional to realize.For instance; All that can cooperation mode use ASIC 208, memory 212, API 210 and local data base 214 load, store and carry out various function disclosed herein, and therefore can be with the assignment of logical that is used to carry out said function in various elements.Perhaps, can incorporate in the discrete component functional.Therefore, should think that the characteristic that accesses terminal among Fig. 3 is merely illustrative, and the invention is not restricted to illustrated characteristic or layout.
Fig. 4 explanation is used to set up the conventional process of given GPRS communication session.In particular, Fig. 4 is illustrated as given GPRS communication session PDP context activating and gives AT to support the usual manner of given GPRS communication session resource allocation based on the PDP Context that is activated.
Referring to Fig. 4, AT 1 determines whether to carry out GPRS communication session (400).For instance, if the GPRS communication session is called out (for example, multicast call etc.) corresponding to group's PoC (PTT), so 400 confirm the starting that can use corresponding to the PTT on the AT 1.If AT 1 confirms to carry out the GPRS communication session, require AT 1 to be said session activation PDP Context so.Therefore, AT 1 allocation activation PDP Context request message, it comprises the information (405) relevant with the AT that is used for the GPRS communication session 1.For instance, PDP context activating request message can be through the QoS that asks that is configured to comprise said session, the access point numbering (APN) (for example, it can obtain after the DNS inquiry) of GGSN 165 etc.Dynamically assigned by GGSN if wrap in the pdp address that is addressed to during the GPRS communication session, in PDP context activating request message, the pdp address field is empty, is not activated as yet because be used for the PDP Context of the session of AT 1 so.
Be in 405 that after the allocation activation PDP Context request message, AT 1 will send to SGSN 160 (410) through allocation activation PDP request message via RAN 120.SGSN 160 receives the PDP context activating request message, and will create the PDP Context request message and send to GGSN 165 (415).GGSN 165 receives from SGSN 160 and creates the PDP Context request message, and is the communication session PDP context activating (420) of AT 1.The activation of PDP Context is included as the communication session appointment pdp address (for example, IPv6 address) of AT 1 in 420.GGSN 165 will create PDP Context and accept message and send back to SGSN 160 (425), and its indication is accepted from 415 establishment PDP Context request message, and also passes on the pdp address of the communication session of AT 1.SGSN 160 will be used for the communication session of AT 1 based on PDP Context RAB assignment request sends to RAN 120 (430).For instance, SGSN 160 can use RAB parameter field instruction RAN 120 in the RAB assignment request about the QoS resource of given grade, and during communication session, to distribute to AT 1, said RAB parameter field contains the qos requirement to the communication link of AT 1.RAN 120 receives the RAB assignment request, and sets up message (435) based on the radio bearer that the RAB parameter is sent the communication session that is used for AT 1.AT 1 receives radio bearer and sets up message, correspondingly disposes radio bearer, and sets up completion message to send to RAN 120 (440) radio bearer.RAN 120 then assigns response message to send back to SGSN 160 (445) RAB.At this moment, SGSN 160 accepts message via RAN 120 with PDP context activating and sends to AT 1 (450), and said message indication is accepted from 410 PDP context activating request message, and also passes on the pdp address of the communication session of AT 1.
PDP context activating receiving in 450 is accepted message (for example, its reception and registration is ready to use in the pdp address of said session) afterwards, and AT 1 can begin to send and receive the message (455) relevant with the communication session of being set up.
As be understood by those skilled in the art that; Though PDP Context (for example can be indicated the PDP type; Main or less important), PDP parameter (for example ToS, APN, QoS, pdp address etc.), identifier (for example NSAPI, TI, TEID etc.) and/or other parameter, but conventional PDP Context does not comprise with the application that is associated with the GPRS communication session that just is being activated and supported by AT 1 or serves relevant information.For instance, if the GPRS communication session is wanted PTT calling signaling initial or that participate in corresponding to AT 1, the PTT calling signaling is the interactive application to delay-sensitive so.Yet SGSN 160 and GGSN 165 can recognize that the interaction that is applied as initiation is called out, but not necessarily have the special knowledge about the essence of using, and therefore not know said session be to postponing or time-sensitive.Therefore, SGSN 160 and GGSN 165 might not grant AT 1 with positive resource, and this may make the performance degradation of the communication session of AT 1.
The embodiment that hereinafter will be described in more detail is to will using or service-specific information conveys to RAN 120, SGSN 160 and/or GGSN 165 from the AT that asks PDP context activation, and application of being passed on or service-specific information are stored in the PDP Context.RAN 120, SGSN160 and/or GGSN 165 can follow at least in part based on using or service-specific information is given resource allocation the request AT of communication session.
Therefore, Fig. 5 explanation is according to the process that is used to set up given GPRS communication session of the embodiment of the invention.In particular, Fig. 5 is illustrated as given GPRS communication session PDP context activating (it is through being configured to comprise application relevant with session or service-specific information) and gives AT to support the mode of given GPRS communication session resource allocation based on the PDP Context that is activated.
Referring to Fig. 5, AT 1 determines whether to carry out GPRS communication session (500).For instance, if the GPRS communication session is called out (for example, multicast call etc.) corresponding to group's PoC (PTT), so 500 confirm can push the PTT button on the AT 1 corresponding to the user of AT 1.In 500, confirm to carry out after the GPRS communication session, AT 1 confirms (if possible) application or service-specific information (505) relevant with communication session.As used herein, with using or service-specific information is defined as and service of being supported by AT 1 or the relevant and any information that be associated with communication session of application.About the PTT of group call instance, application or service-specific information can be the understanding to group or PTT calling corresponding to communication session.
In 510, AT 1 determines whether application or the service-specific information confirmed in 505 are conveyed to SGSN 160 and/or GGSN 165.For instance, if the application that is associated with the GPRS communication session not to delay-sensitive, AT 1 can confirm not send application-specific information in 510 so, and process can advance to 405 of Fig. 4, and is as indicated above.Otherwise, if application that AT 1 confirms in 505, to confirm or service-specific information convey to SGSN 160 and/or GGSN 165 (for example, the application that is associated with the GPRS communication session whether be to delay-sensitive etc.), process advances to 515 so.
In 515, AT 1 allocation activation PDP Context request message, it comprises the information relevant with the AT that is used for the GPRS communication session 1 (be similar to Fig. 4 405).For instance, PDP context activating request message can be through the APN (APN) of the AT 1 that is configured to comprise GGSN 165 (for example, its can acquisition after the DNS inquiry) etc.In PDP context activating request message, it is empty wrapping in the pdp address field that is addressed to during the GPRS communication session, is not activated as yet because be used for the PDP Context of the session of AT 1.
Yet, Fig. 5 515 in, PDP context activating request message further through be configured to indicator diagram 5 505 in application or the service-specific information relevant confirmed with communication session.Application or service-specific information can be included in the PDP context activating request message in a number of ways.For instance, can revise one or more fields in the PDP context activating request message, indication is used or the flag of service-specific information to comprise.
In particular instance more; AT 1 can be in 515 allocation activation PDP Context request message (for example; Be used for main PDP Context) and/or (for example activate less important PDP Context request; Be used for less important PDP Context), to comprise special QoS configuration, make GGSN 165 and SGSN 160 to discern AT 1 uniquely based on particular arrangement.And; Because will (utilizing the RAB parameter field) in the RAB assignment request message with QoS, SGSN 160 is delivered to the RNC (for example, seeing 540, hereinafter) at RAN 120 places; Therefore RNC or RAN 120 also can dispose based on special QoS and discern AT 1; Therefore and distribute the required UTRAN resource of multimedia application (for example, positive UTRAN_DRX_CYCLE, it is used for confirming paging circulation at AT 1 place).
In a further example, in 515, the NSAPI that AT 1 can select to be kept (for example, 0 to 4, it is under an embargo and does not use according to standard is current), and the said NSAPI that keeps is included in PDP context activating request and/or activates in the less important PDP Context request.With the same in the instance formerly, GGSN 165 and SGSN 160 will read message, and can be uniquely the NSAPI that is kept be identified as and be used for specific multimedia application (multimedia application of the QoS of the high-grade or positive grade of for example known needs).And because the RAB ID in the RAB assignment request (for example, seeing 540, hereinafter) is forced the equal values of NSAPI, so RAN 120 can discern AT 1 based on RAB ID.
In alternate embodiment, can special or pre-determined bit be embedded in the NSAPI information element (IE).NSAPI IE is 8 positions, and wherein preceding 4 LSB are used to deliver NSAPI, and back 4 LSB are spare bit.Therefore, in this example, 4 spare biies among the AT 1 NSAPI IE capable of using supply SGSN 160 and GGSN 165 identification AT 1.Because according to standard RAB ID IE=NSAPI IE, so RAN 120 can discern AT 1, and can positive UTRAN_DRX CYCLE be assigned to AT 1.
In another alternate example, APN is included in being used in the PDP context activating request to select the string parameter of GGSN 165.Therefore, in 515, AT 1 can put into APN with keyword, is used to discern AT 1 and has high qos requirement.GGSN 165 and SGSN 160 can receive APN in PDP context activating request.Yet for the application-specific in this instance, RAN 120 can not necessarily be apprised of the high qos requirement (for example, although RAN 120 can be instructed via distributing positive QoS set point from the RAB assignment request message of SGSN in the hereinafter 540) of AT 1.
Be in 515 after the allocation activation PDP Context request message that AT 1 will send to SGSN 160 (520) through the activation PDP request message of configuration via RAN 120.SGSN 160 receives the PDP context activating request message, and will create PDP Context request message (it also comprises application or service-specific information) and send to GGSN 165 (525).GGSN 165 receives from SGSN 160 and creates the PDP Context request message, and is the communication session PDP context activating (530) of AT 1.The activation of PDP Context is included as the communication session appointment pdp address (for example, IPv6 address) of AT 1 in 530.530 activation also comprises the application of the communication session that is used for AT 1 or service-specific information is stored in PDP Context.
GGSN 165 will create PDP Context and accept message and send back to SGSN 160 (535), and its indication is accepted from 525 establishment PDP Context request message, and also passes on pdp address and the application or the service-specific information of the communication session of AT 1.SGSN 160 will be used for the communication session of AT 1 based on PDP Context RAB assignment request sends to RAN 120 (540).For instance, SGSN 160 can use RAB parameter field instruction RAN 120 in the RAB assignment request about the QoS resource of given grade, and during communication session, to distribute to AT 1, said RAB parameter field contains the qos requirement to the communication link of AT 1.If SGSN 160 indications in this instance of application or service-specific information need high-grade QoS resource, SGSN 160 can instruct RAN 120 to give AT 1 than the QoS resource allocation of the amount that the amount of distribution will be high in 540 originally so.In another example, if use or the communication session of SGSN 160 indication which ATs 1 of service-specific information in this instance can be benefited from the paging circulation positive than tool, the frequency waken up of AT 1 can increase so.
RAN 120 receives the RAB assignment request, and sets up message (545) based on the radio bearer that the RAB parameter is sent the communication session that is used for AT 1.AT 1 receives radio bearer and sets up message, and sets up completion message to send to RAN 120 (550) radio bearer.RAN 120 then assigns response message to send back to SGSN 160 (555) RAB.
At this moment, SGSN 160 accepts message via RAN 120 with PDP context activating and sends to AT 1 (560), and said message indication is accepted from 520 PDP context activating request message, and also passes on the pdp address of the communication session that is used for AT 1.Accept message (for example, its reception and registration is ready to use in the pdp address of said session) afterwards receiving PDP context activating, AT 1 can begin to send and receive the message (565) relevant with the communication session of being set up.
